Programming note: See more of Dana Bash's interview with Gabby Giffords and Mark Kelly on AC360° at 8 and 10 p.m. ET Tuesday night.

Former Congresswoman Gabby Giffords and her husband, Mark Kelly, tell CNN's Dana Bash that they continue to own guns for recreation. Giffords was severely wounded during a 2011 shooting rampage that injured 12 others and killed six in Tucson.

For target practice, Kelly uses the same type of gun Giffords was shot with, a 9mm Glock, but with a magazine that can hold 17 rounds. The Tucson shooter had a magazine that held 33 rounds.

They believe they have credibility in the gun control debate because they are long-time gun owners who support Second Amendment rights. The couple is campaigning for stricter gun laws, including universal background checks, to prevent guns from getting in to the wrong hands.
